Using the extended Poincare-Lighthill-Kuo reductive perturbation method to study the small-amplitude ion acoustic solitary wave dynamics (propagation and interaction), it is shown that in the Thomas-Fermi magnetoplasma consisting of inertial-less degenerate electrons and positrons and isothermal ions, distinctive features emerge when the ultrarelativistic degeneracy pressure applies to electrons and positrons. Calculations show that ion-acoustic solitary waves may interact differently in such plasmas under ultrarelativistic degeneracy pressure.
